I just purchased a sti intercooler for my 06 wrx that has just a few mods, access port ots stage 2 map, cobb intake, bov, and down pipe. Im putting on the intercooler in a few days, but just wanted to get a sense of what gains should be expected with this intercooler and my setup? thanks!!

first thing let me tell you that the ots stage 2 map does not call for a bov. you need to put the stock bypass valve on,or get a street tune to make a realtime tune with that bov that you have on there. im running everything you have except i have the stock bypass valve with a full catless exhaust system (up pipe also).i put a sti top mount on months after i was stage 2 ots map and really didnt notice anything. but i did just recently got my car street tuned on stage 2 and now im pulling 18.5 lbs boost on the stock tdo4(dont know what turbo came with your wrx,it may be the same). hope this helps
